The links don't say which Heiner Bartels was transferred away from JG 5.
According to Walther Schuck's book "Abschuss", Bartels, an Austrian from Linz, was famous for pranks and drinking, but after getting his Knight's cross, he apparently went a bit too far.
In Petsamo, November 1942:
First he woke up Schuck, and made him drink Cognac, each time pouring the liquor over his new Knight's cross, to "baptize" it. Meanwhile Kurt Dylewski, his inseparable Wingman (also very drunk) started playing the guitar extremely loud and extremely false.
After leaving Schuck (and three empty cognac bottles) Bartels went on a drunken rampage:
First, he tried to steal a truck, but the driver had taken the key. The driver woke up and pulled the drunken Bartels out of the cabin and started beating him up.
After realizing whom he was beating up, the driver panicked and ran into the enlisted quarters, went to bed and pretended to sleep.
Bartels followed him and searched the barracks for the drivers wet boots, finally finding them and promptly beating the crap out of the guy in the bed next to the boots.
The original culprit meanwhile had the upper bed and hid successfully...
After that, Bartels and Dylewski went to the civilian quarters and invaded the billet of the lapland women who were employed in cleaning and washing duties in Petsamo.
He lifted every blanket and each time he shouted (in broad austrian dialect):
"Pfui Teifi, A so a brutaler Wahnsinn, s'stinkt furchtbor noch Kas! Ois Kas, gonz a oiter Kas!"
(roughly translated "wow, it really smells like cheese under here, terrible old cheese!")
The semi-nomadic laplanders had a bit of a strong smell apparently.
Still not ready to call it a night, Bartels went into the stables, and pulled out one of the mules.
He led the mule to the billet of the "Spieß" (Company Sergeant) of his staffel, made it stand halfly on the sleeping man's bed. As Bartels was a Butcher in Civilian life, he knew how to treat animals and the poor mule emptied its bowels over the sleeping Feldwebel, covering him and the entire bed with #%&*$#..
After that, Bartels finally went to sleep.

This was too much even for JG 5, where it was pretty usual to fire pistols through walls at snoring people and Gruppenkommandeur Horst Carganico had to report him for court martial.
Highly decorated as he was, Bartels escaped degradation and was just transferred from the Artic to Greece.
His last flight was typical for cocky, unruly Bartels, as he was due for leave but just wanted to score his 100th kill before going on leave....
Dylewski had allready gone on leave, but Bartels stayed for one more mission.
